Next month Britain is expected to go into a shopping frenzy with the arrival of Black Friday.

The event is known as the biggest shopping day of the year. It's a time customers tend to buy electricals - like TVs and laptops - and stock up on Christmas gifts at slashed prices.

Typically retailers keep tight-lipped about their reductions, and this year is no exception.

However, the deals tend to be similar each year, so we can predict which kind of products will be on offer.

Here's where you will be able to find the best sales.

When is Black Friday?

Black Friday is on November 24.

Amazon

Last year, Amazon spread its Black Friday deals over 10 days, with thousands of offers for its customers.

You can expect deals on Amazon's own-brand products like the Echo, Kindle and Fire TV Stick.

Amazon also do flash sales known as Lightning Deals. These are time-limited offers which will appear on the site unannounced for a 24-hour period. To keep on top of these check the site regularly.

There will also be exclusive offers for Amazon Prime members.

Last year Tesco hosted 11 days worth of sales with offers on electricals, gadgets, toys, homeware and more.

Tesco no longer sells non-grocery items like homeware and electricals online, and it's unclear whether it will make an exception for Black Friday.

In 2016 the most bought items on Black Friday included Dyson vacuums, LG and Samsung TVs, HP laptops and coffee machines.

Boots

Boots will have some great offers this Black Friday on gift sets, electricals, beauty products and perfumes.

According to the Mirror, this year there will also be big discounts on a wide range of beauty Advent calendars, from premium brands like Liz Earle.

Shoppers can also expect discounts on Yankee Candle products.

Currys and PC World

Shoppers can expect deals on coffee machines, vacuum cleaners and laptops. Last year offers started appearing online at 12am.

According to the retailer, in 2016, five orders per second were placed online during peak times.

Argos

According to the Mirror, Argos is expected to announce a preview of its Black Friday deals at the beginning of November.

Last year the retailer reduced prices on some of the top-selling toys of 2017, including Hatchimals, Luvabella and LOL Surprise!

In 2018 shoppers can expect slashed prices on homeware and technology, as well as gifts and toys.

John Lewis

With its 'Never Knowingly Undersold' tag line the department store promises to price match its competitors throughout the year.

"Our price promise in action means that even during our Black Friday event we'll be checking and responding to competitors' promotions and prices, so it's worth taking a look online from time to time to see what's new in our Black Friday offers. You may not always see these offers in store as it’s quicker to make price changes online . . ." a statement reads on the retailer's website.
